Fields

default_model: String

language: String

session_dir: String

hop_ms: u32

min_window_ms: u32

engine_prefer: String

audio_default_source: String

input_device: Option<String>

Device name chosen by the user. None = use the OS default input. Missing-from-config (old configs) deserializes to None.

input_device_kind: Option<AudioSessionKind>

Kind of the saved device. None for old configs / default input. Lets start_recording pick the right capture path without having to re-enumerate and match by name first.

last_app_id: Option<String>

Last app the picker’s Apps pane was on. None = no app paired. Bundle id (macOS) or PID-stringified value (Windows). Restored at next launch so the user’s app cursor lands where they left it.

refinement_model: Option<String>

Optional background refinement model. When set, a second whisper engine runs in parallel on wider non-overlapping windows with beam search and emits higher-quality segments that replace the streaming output in the UI. None disables refinement.

refinement_window_ms: u32

Window length (ms) of audio fed to each refinement pass.

refinement_beam_size: u8

Beam size for refinement. 1 = greedy (fastest, lowest quality).

voicebird_api_key: String

Voice Bird Web API key. Stored in plaintext in config.toml — file permissions are the only protection. Empty string = unset.

voicebird_server_url: String

WebSocket URL of the Voice Bird Web /api/audio/stream endpoint the desktop client streams to when cloud_broadcast_enabled is true. Defaults to the hosted production server.

cloud_broadcast_enabled: bool

When true, recordings stream PCM to voicebird_server_url and transcripts are produced by the cloud model. The local Whisper engine is bypassed and no session files are written to disk — the recording lives entirely on the user’s voicebird.app account. When false (default), the local engine runs and writes ~/voice-bird/sessions/<ts>/.

source_overrides: BTreeMap<String, SourceSettingsOverride>

Per-source setting overrides. Key is the result of source_id or device_source_id; value carries the cloud/language/model to use when starting a section for that source. When absent for a given source, [effective_settings] falls back to the global fields above.

Implementations

impl AppConfig

pub fn config_path() -> Result<PathBuf>

pub fn load() -> Result<Self>

pub fn save(&self) -> Result<()>

pub fn load_from(path: &Path) -> Result<Self>

pub fn save_to(&self, path: &Path) -> Result<()>

pub fn session_dir_expanded(&self) -> String

pub fn effective_override(&self, key: &str) -> SourceSettingsOverride

Effective per-source settings: the saved override for key if present, else the global defaults from this config. The returned override carries the cloud_on, language, model triple a section actually uses at start time.

pub fn upsert_source_override( &mut self, key: String, ov: SourceSettingsOverride, )

Convenience: persist or update one source’s override and save.
